VIENNA - Illegal online pharmacies are using social media to attract young customers and sell them illicit drugs and medicines, a UN agency warned Tuesday. “Illegal Internet pharmacies have started to use social media to get customers for their websites,” Hamid Ghodse, president of the International Narcotics Control Board, said in the agency’s annual report published Tuesday. This “can put large, and especially young, audiences at risk of dangerous products, given that the World Health Organisation has found that over half of the medicines from illegal Internet pharmacies are counterfeit,” he said. Illegal online pharmacies often pretend to be legal but in fact smuggle illicit products to their customers, the INCB found, urging governments to close them down.
